LOOM-PICKER.

SPECIFICATION forming part of Letters Patent No. 663,020, dated December 4, 1900.

Application filed September 17, 1900. Serial No- 30,218. (No model.)

To all whom it may concern.-

Be it known that we, LAURENCE Z.FORGUES and ALPHONSE LAVOIE, citizens of the United States, residing at Salem, in the county of Essex and State of Massachusetts, have invent ed new and useful Improvements in Loom- Pickers, of which the following is a specification.

This invention relates to improvements in loom-pickers, and it is carried out as follows, reference being bad the accompanying drawings, wherein Figure 1 represents a side elevation of the invention. Fig. 2 represents a rear View of the same. Fig. 3 represents a vertical longitudinal section. Fig. 4 represents a crosssection on the line 4 4 shown in Fig. 1. Fig. 5 represents a vertical section on the line 5 5 shown in Fig. l, and Fig. 6 represents a detail rear elevation of the picker-stafi spring.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents the loom picker-stafi, as usual, adapted to receive the forked metal binder B B, which incloses the stafi A on two opposite sides, as shown. In one piece with said binder is made the pickerholding shell or casing G, which contains the picker or filling D, which may be made of any suitable material without departing from the essence of our invention.

The shell or casing O has at its front end a perforation C, so as to expose the filling D where it comes in contact with the shuttle end during the weaving operation. The said shell or casing O is preferably provided at its under and upper sides with the respective inwardly-turned lips C O and O for the purpose of retaining the filling D in place within said casing C after being inserted therein.

The rear ends of the forked metal binder portions B B are provided with vertical ribs or guides B B, adapted to receive a correspondinglygrooved nutblock or lockingblock E, as shown. Said block E is internally screw-threaded, and through it is screwed a fastening-screw F, the inner end of which is preferably made conical or tapering and 50 caused to bear against the upper end of a spring G, as shown. In practice we prefer to make on the outside of the upper end of said spring G a countersunk orconical recess g, as shown in Figs. 3, 4, and 6, for receiving the pointed or conical end of the screw F. A corresponding projection g is made on the spring G opposite to the countersunk recess g, so as to cause it to be pressed into the rear portion of the staff A when the spring G is forced against the rear of said staff by the turning of the screw F, as shown in Figs. 3 and 4,

and in this manner the said spring is caused to be firmly secured to the rear of the stafi.

In practice we prefer to provide the upper end of the spring G with side projections G G, adapted to rest upon the upper edges of the metal binder portions B B, thus additionally preventing said spring from working downward.

The filling D may readily be inserted with in the shell or casing 0 previous to placing the latter on the staff, afterwhich the device is placed in its proper position on said staff, the grooved block E is interlocked with the ribs or guides B B, the upper end of the spring G is placed in position back of the staff A, after which the binder-screw F is tightened, causing the filling D to be firmly held and compressed between the front end of the casing G and front portion of the staff A at the same time as the upper end of the spring G is caused to be held firmly in position against the rear of the stafi by the pressure of the screw F, as shown in the drawings.

During the backward motion of the staff its spring G comes in contact with the frame of the machine, thus preventing said staff from striking the latter, and by the employment of such spring we are able to dispense with the usual back or check strap ordinarily used in connection with pickerstaffs.

The device is very simple, strong,and durable and can readily be applied to and removed from picker-stads as occasions may require.

What we desire to secure by Letters Patent and claim is-- In a loom-picker, the combination with a picker-staff of a metal shell or casing G, a filling contained therein, forked metal binders B, B, made integral with said casing, a nut or our hands in presence of two subscribing Witblock E, adapted to interlock with the opennesses. ended portion of the binder and provided with a set-screw F, and a spring G interposed 5 between the rear portion of the staff and the LAURENCE ZQFORGUES.
